During operation, the upper die holder 1 and the lower die holder 2 are clamped, then molten metal is injected into a die cavity 22 in the lower die holder 2 from a pouring opening 11, the molten metal is die-cast into a thin-wall piece, then cooling liquid is introduced into a cooling cavity 23 through a hose 24 to cool the thin-wall piece, after cooling is finished, the upper die holder 1 and the lower die holder 2 are opened, the jacking plate 3 moves upwards under the action of pressure in the cooling cavity 23, the thin-wall piece is pushed out of the die cavity 22, and the thin-wall piece is demolded;
meanwhile, as the cooling cavity 23 is arranged below the jacking plate 3, when the thin-wall part is cooled, the heat dissipation of the thin-wall part can be accelerated through the relatively large area of the jacking plate 3, and the forming of the thin-wall part is promoted, so that the cooling effect and efficiency of the thin-wall part are improved;
Meanwhile, the control of the controller on the water pump enables the cooling liquid to form larger positive pressure in the cooling cavity 23, so that after the thin-wall part is cooled and the upper die holder 1 and the lower die holder 2 are opened, the jacking plate 3 moves upwards under the positive pressure effect to push the thin-wall part outwards, the thin-wall part is conveniently demolded from the die, and the demolding efficiency is improved, meanwhile, when the thin-wall part is pushed outwards, the jacking plate 3 has larger contact area on the thin-wall part and the thin-wall part is uniformly stressed, thereby avoiding the situation that the thin-wall part is not completely shaped, and rod-shaped parts for ejection generate scratches and indentations on the surface of the thin-wall part to influence the quality of the thin-wall part;

As an embodiment of the invention, the cooling liquid in the cooling cavity 23 is emptied during die casting;
During die casting, the cooling liquid in the cooling cavity 23 can be emptied in advance, so that when molten metal is prevented from being injected into the cavity 22, the molten metal is prevented from being rapidly dispersed in temperature, so that the molten metal is cooled too quickly, the forming or defect generation of the thin-wall part is influenced, the quality of the thin-wall part is influenced, meanwhile, as the thickness of the cooling liquid emptied in the cooling cavity 23 and the thickness of the jacking plate 3 are relatively thinner, the jacking plate 3 can absorb relatively less heat or conveniently lift the temperature of the jacking plate 3 in the die casting process, the preheating of a die is completed, and the plasticity of the injected molten metal and the quality of the thin-wall part are prevented from being influenced.
The specific working procedure is as follows:
During operation, the upper die holder 1 and the lower die holder 2 are clamped, then molten metal is injected into a die cavity 22 in the lower die holder 2 from a pouring opening 11, the molten metal is die-cast into a thin-wall part, then cooling liquid is introduced into a cooling cavity 23 through a hose 24 to cool the thin-wall part, after cooling is finished, the upper die holder 1 and the lower die holder 2 are opened, so that a jacking plate 3 moves upwards under the action of pressure in the cooling cavity 23, and the thin-wall part is pushed out of the die cavity 22 for external demoulding;
Meanwhile, as the cooling cavity 23 is arranged below the jacking plate 3, when the thin-wall part is cooled through the relatively large area of the jacking plate 3;
Meanwhile, the cooling liquid forms larger positive pressure in the cooling cavity 23 through the control of the controller on the water pump, so that after the thin-wall part is cooled and the upper die holder 1 and the lower die holder 2 are opened, the jacking plate 3 moves upwards under the positive pressure effect to push the thin-wall part outwards, and meanwhile, the contact area of the jacking plate 3 on the thin-wall part is large and the stress on the thin-wall part is uniform;
Simultaneously, after the thin-wall part is demolded, the controller controls an external water pump to pump out the cooling liquid in the cooling cavity 23, so that the inside of the cooling cavity 23 becomes negative pressure, and the jacking plate 3 returns to the original position;
a reinforcing plate 31 is arranged on the lower surface of the jacking plate 3, so that the reinforcing plate 31 can be positioned between the jacking plate 3 and the bottom surface of the cooling cavity 23 during die casting, and the middle position of the jacking plate 3 is supported and supported;
Meanwhile, by installing the reinforcing plate 31 on the lower surface of the jacking plate 3, the contact area of the jacking plate 3 with the cooling liquid in the cooling cavity 23 can be increased, heat exchange is accelerated when the thin-wall part is cooled, and cooling and forming of the thin-wall part are promoted;
The jacking plate 3 is provided with the jacking block 32, during the demolding process of the thin-wall part, when the jacking plate 3 pushes the thin-wall part outwards towards the cavity 22, one end of the jacking block 32 positioned in the cooling cavity 23 is also subjected to the positive pressure effect of cooling liquid, so that the jacking block 32 is ejected towards the thin-wall part, the jacking block 32 is utilized to further promote the separation of the thin-wall part and the jacking plate 3, and simultaneously, after the demolding is completed, the jacking block 32 is returned to the original position when the jacking plate 3 is influenced by the negative pressure in the cooling cavity 23;
After cooling liquid is introduced into the cooling cavity 23, the temperature of the deformation rod 322 is rapidly reduced, so that the deformation rod 322 is deformed and drives the ejector block 32 to eject outwards, meanwhile, a lantern ring 323 is arranged on the baffle 321, the deformation rod 322 is isolated by the lantern ring 323, when the cooling liquid is introduced into the cooling cavity 23, the cooling liquid cannot contact the deformation rod 322 for the first time, the deformation time of the deformation rod 322 is delayed, and after the thin-wall part is cooled, the ejector block 32 is used for separating the thin-wall part from the jacking plate 3;
The collar 323 with relatively thin thickness is made of the high-temperature-resistant cloth, so that the collar 323 can move when the top block 32 moves, meanwhile, due to gaps on the surface of the high-temperature-resistant cloth, cooling liquid can pass through the high-temperature-resistant cloth, so that the deformation rod 322 is cooled, and simultaneously, when die casting is continuously carried out, the inside and the outside of a space surrounded by the high-temperature-resistant cloth are relatively isolated, and the exchange between the cooling liquid and heat in the inside and outside space is delayed;
Through arranging a plurality of groups of hoses 24, the introduced multi-strand cooling liquid can flow in the spaces between different reinforcing plates 31 without mutual interference and mixing, so that the temperature difference between the cooling liquid and the jacking plate 3 and between the cooling liquid and the reinforcing plates 31 is increased, the heat exchange speed is accelerated, and meanwhile, when the thin-wall part is relatively large or the thin-wall part is a partial thin wall, the temperature of the introduced cooling liquid is changed through different hoses 24, so that the temperature of each part of the thin-wall part is relatively uniformly reduced;
the sealing effect between the jacking plate 3 and the inner wall of the cavity 22 is improved through the mutual matching of the step groove 33 between the jacking plate 3 and the mounting table 25;
meanwhile, by arranging the guide inclined plane 331 at the downward end of the step groove 33, when the jacking plate 3 returns to the original position, the guide inclined plane 331 contacts the corresponding inclined plane on the mounting table 25, so as to guide the process that the jacking plate 3 approaches the mounting table 25 and is attached to the mounting table 25;
during die casting, the cooling liquid in the cooling cavity 23 is emptied in advance, so that the phenomenon that the temperature of the molten metal is rapidly diffused when the molten metal is injected into the die cavity 22, and the molten metal is cooled too fast to influence the forming or defect generation of the thin-wall part is avoided.
